The equivalent of a H-Bomb coming from one's ass; these farts have the ability to linger for minutes, and can even spread through multiple rooms.

Beware of anyone with protein farts.

Bill: ...dude, did you jus- WTF IS THAT SMELL?
John: PROTEIN FART, RUN!!!!!!!!!!!!!!
Bill: *runs to his room* ARGHH, IT FOLLOWED ME IN HERE.
Jack: *opens his room* WTF IS THIS SMELL COMING INTO MY ROOM?
John: Sorry guys, I can't help it.
